Figure 2

The evolutionary relationship inferred using Neighbor-Joining method in 3′ end of 18S. Percentages of replicate trees from the bootstrap test (500 replicates) are shown next to branches. The distances were computed using Jukes-Cantor method. The rate variation among sites was modeled with a gamma distribution (shape parameter = 1). The analysis involved a total of 31 nucleotide sequences. All positions containing gaps and missing data were eliminated from analysis. A total of 436 positions were included in the final dataset. These positions corresponded to nucleotides between positions 1076 to 1549 in the B. divergens sequence (FJ944825).
